"WebX-ray fluorescence is a well-established technique which analyses secondary x-ray emitted from a sample whilst it is irradiated. The secondary x-rays are characteristic of a particular element, so analsis of the XRF spectrum can determine the composition of a sample. XRF is particularly valuable when identifying heavy metals within a sample. " - Secondary x rays
